title: Development of hypervitaminosis A in a patient on long-term parenteral hyperalimentation.
abstract: A four and one-half year old boy with intestinal pseudo-obstruction who had been maintained on parenteral hyperalimentation for one year developed classical signs of hypervitaminosis A. This diagnosis was confirmed radiographically; serum vitamin A levels were five times normal. The patient had a dramatic response to withdrawal of vitamin A from the hyperalimentation fluid.
